Abstract
A method of making a laminate sheet having a film layer and a fabric layer. The method includes the step of bonding a film layer to a fabric layer in order to form a laminate sheet such that the laminate sheet includes at least one high-bond region whereat the strength of the bond between the film and fabric layers is greater than other regions of the laminate sheet. The method further includes the step of stretching the laminate sheet such that the high-bond regions are either not stretched or are only partially stretched. A method of making a diaper backsheet, as well as a stretched laminate of a polymeric film and a fabric web, is also provided.
